bpf, sockmap: Test FIONREAD returns correct bytes in rx buffer with drops
When BPF program drops pkts the sockmap logic 'eats' the packet and updates copied_seq. In the PASS case where the sk_buff is accepted we update copied_seq from recvmsg path so we need a new test to handle the drop case. Original patch series broke this resulting in test_sockmap_skb_verdict_fionread:PASS:ioctl(FIONREAD) error 0 nsec test_sockmap_skb_verdict_fionread:FAIL:ioctl(FIONREAD) unexpected ioctl(FIONREAD): actual 1503041772 != expected 256 After updated patch with fix.

bpf, sockmap: Test FIONREAD returns correct bytes in rx buffer
A bug was reported where ioctl(FIONREAD) returned zero even though the socket with a SK_SKB verdict program attached had bytes in the msg queue. The result is programs may hang or more likely try to recover, but use suboptimal buffer sizes. Add a test to check that ioctl(FIONREAD) returns the correct number of bytes.

bpf, sockmap: Build helper to create connected socket pair
A common operation for testing is to spin up a pair of sockets that are connected. Then we can use these to run specific tests that need to send data, check BPF programs and so on.

perf tools fixes for v6.4:
- Fail graciously if BUILD_BPF_SKEL=1 is specified and clang isn't available.
- Add empty 'struct rq' to 'perf lock contention' to satisfy libbpf 'runqueue'
type verification. This feature is built only with BUILD_BPF_SKEL=1.
- Make vmlinux.h use bpf.h and perf_event.h in source directory, not system
ones that may be old and not have things like 'union perf_sample_weight'.
- Add system include paths to BPF builds to pick things missing in the headers
included by clang -target bpf.
- Update various header copies with the kernel sources.
- Change divide by zero and not supported events behavior to show 'nan'/'not
counted' in 'perf stat' output. This happens when using things like
'perf stat -M TopdownL2 true', involving JSON metrics.
- Update no event/metric expectations affected by using JSON metrics in
'perf stat -ddd' perf test.
- Avoid segv with 'perf stat --topdown' for metrics without a group.
- Do not assume which events may have a PMU name, allowing the logic to keep an
AUX event group together. Makes this usecase work again:

- Add a check for the above use case in 'perf test test_intel_pt'.
- Fix build with refcount checking on arm64, it was still accessing fields that
need to be wrapped so that the refcounted struct gets checked.
- Fix contextid validation in ARM's CS-ETM, so that older kernels without that
field can still be supported.
- Skip unsupported aggregation for stat events found in perf.data files in 'perf script'.
- Add stat test for record and script to check the previous problem.
- Remove needless debuginfod queries from 'perf test java symbol', this was
just making the test take a long time to complete.
- Address python SafeConfigParser() deprecation warning in 'perf test attr'.
- Fix __NR_execve undeclared on i386 'perf bench syscall' build error.

Power management fixes for 6.4-rc3
- Get rid of a warning message printed by the ACPI cpufreq driver
after recent changes in it when anohter CPU performance scaling
driver is registered already when it starts (Petr Pavlu).
- Make cpupower read TSC on each CPU right before reading MPERF so as
to reduce the potential time difference between the TSC and MPERF
accesses and improve the C0 percentage calculation (Wyes Karny).
- Fix a possible file handle leak and clean up the code in the
sysfs_get_enabled() function in cpupower (Hao Zeng).

cxl: Move cxl_await_media_ready() to before capacity info retrieval
Move cxl_await_media_ready() to cxl_pci probe before driver starts issuing
IDENTIFY and retrieving memory device information to ensure that the
device is ready to provide the information. Allow cxl_pci_probe() to succeed
even if media is not ready. Cache the media failure in cxlds and don't ask
the device for any media information.
The rationale for proceeding in the !media_ready case is to allow for
mailbox operations to interrogate and/or remediate the device. After
media is repaired then rebinding the cxl_pci driver is expected to
restart the capacity scan.

cxl/port: Enable the HDM decoder capability for switch ports
Derick noticed, when testing hot plug, that hot-add behaves nominally
after a removal. However, if the hot-add is done without a prior
removal, CXL.mem accesses fail. It turns out that the original
implementation of the port driver and region programming wrongly assumed
that platform-firmware always enables the host-bridge HDM decoder
capability. Add support turning on switch-level HDM decoders in the case
where platform-firmware has not.
The implementation is careful to only arrange for the enable to be
undone if the current instance of the driver was the one that did the
enable. This is to interoperate with platform-firmware that may expect
CXL.mem to remain active after the driver is shutdown. This comes at the
cost of potentially not shutting down the enable on kexec flows, but it
is mitigated by the fact that the related HDM decoders still need to be
enabled on an individual basis.

selftets: seg6: disable rp_filter by default in srv6_end_dt4_l3vpn_test
On some distributions, the rp_filter is automatically set (=1) by
default on a netdev basis (also on VRFs).
In an SRv6 End.DT4 behavior, decapsulated IPv4 packets are routed using
the table associated with the VRF bound to that tunnel. During lookup
operations, the rp_filter can lead to packet loss when activated on the
VRF.
Therefore, we chose to make this selftest more robust by explicitly
disabling the rp_filter during tests (as it is automatically set by some
Linux distributions).

selftests: seg6: disable DAD on IPv6 router cfg for srv6_end_dt4_l3vpn_test
The srv6_end_dt4_l3vpn_test instantiates a virtual network consisting of
several routers (rt-1, rt-2) and hosts.
When the IPv6 addresses of rt-{1,2} routers are configured, the Deduplicate
Address Detection (DAD) kicks in when enabled in the Linux distros running
the selftests. DAD is used to check whether an IPv6 address is already
assigned in a network. Such a mechanism consists of sending an ICMPv6 Echo
Request and waiting for a reply.
As the DAD process could take too long to complete, it may cause the
failing of some tests carried out by the srv6_end_dt4_l3vpn_test script.
To make the srv6_end_dt4_l3vpn_test more robust, we disable DAD on routers
since we configure the virtual network manually and do not need any address
deduplication mechanism at all.

perf lock contention: Add empty 'struct rq' to satisfy libbpf 'runqueue' type verification
If 'struct rq' isn't defined in lock_contention.bpf.c then the type for
the 'runqueue' variable ends up being a forward declaration
(BTF_KIND_FWD) while the kernel has it defined (BTF_KIND_STRUCT).
This makes libbpf decide it has incompatible types and then fails to
load the BPF skeleton:
# perf lock con -ab sleep 1
libbpf: extern (var ksym) 'runqueues': incompatible types, expected [95] fwd rq, but kernel has [55509] struct rq
libbpf: failed to load object 'lock_contention_bpf'
libbpf: failed to load BPF skeleton 'lock_contention_bpf': -22
Failed to load lock-contention BPF skeleton
lock contention BPF setup failed
#
Add it as an empty struct to satisfy that type verification:
# perf lock con -ab sleep 1
contended total wait max wait avg wait type caller

perf cs-etm: Fix contextid validation
Pre 5.11 kernels don't support 'contextid1' and 'contextid2' so
validation would be skipped. By adding an additional check for
'contextid', old kernels will still have validation done even though
contextid would either be contextid1 or contextid2.
Additionally now that it's possible to override options, an existing bug
in the validation is revealed. 'val' is overwritten by the contextid1
validation, and re-used for contextid2 validation causing it to always
fail. '!val || val != 0x4' is the same as 'val != 0x4' because 0 is also
!= 4, so that expression can be simplified and the temp variable not
overwritten.

perf script: Skip aggregation for stat events
The script command does not support aggregation modes by itself although
that can be achieved using post-processing scripts. Because of this, it
does not allocate memory for aggregated event values.
Upon running perf stat record, the aggregation mode is set in the perf
data file. If the mode is AGGR_GLOBAL, the aggregated event values are
accessed and this leads to a segmentation fault since these were never
allocated to begin with. Set the mode to AGGR_NONE explicitly to avoid
this.
E.g.
$ perf stat record -e cycles true
$ perf script
Before:
Segmentation fault (core dumped)
After:

perf build: Add system include paths to BPF builds
There are insufficient headers in tools/include to satisfy building BPF programs and their header dependencies. Add the system include paths from the non-BPF clang compile so that these headers can be found. This code was taken from: tools/testing/selftests/bpf/Makefile Committer notes: Had to adjust the '#ifndef NO_BPF_SKEL' to '#ifdef BUILD_BPF_SKEL' as reverted that build BPF skels by default. Also cope with the addition of -I$(srctree)/tools/include/uapi done by Yang Jihong so that we prefer using the kernel sources headers instead of older ones in the system.

perf bpf skels: Make vmlinux.h use bpf.h and perf_event.h in source directory
Currently, vmlinux.h uses the bpf.h and perf_event.h header files in the
system path. If the header files in compilation environment are old,
compilation may fail. For example:
/home/yangjihong/linux/tools/perf/util/bpf_skel/.tmp/../vmlinux.h:151:27: error: field has incomplete type 'union perf_sample_weight'
union perf_sample_weight weight;
Use the bpf.h and perf_event.h files in the source code directory to
avoid compilation compatibility problems.

perf evsel: Modify group pmu name for software events
If we have a group of {cycles,faults} then we need the faults software
event to appear to be on the same PMU as cycles so that we don't split
the group in parse_events__sort_events_and_fix_groups.
This case is relatively easy as cycles is the leader and will have a PMU
name. In the reverse case, {faults,cycles} we still need faults to
appear to have the PMU name of cycles but the old behavior is just to
return "cpu".
For hybrid this fails as cycles will be on "cpu_core" or "cpu_atom",
causing faults to be split into a different group.
Change the behavior for software events so that the whole group is
searched for the named PMU.
